San2000, 28 Nov 2015Sir, how to upgrade this phone coz their is no OTA..... And I want to buy this one from India,... moreDo u have the device with u.. If u own one, Get ota files from XDA and flash via stock recovery manually.

My one plus one sim not detected. so I went one plus one authorized service center and they inform me "your SIM slot is broken". only way to repair changing board. so they are asking 75% (14500) of phone cost for repairing my SIM slot. still got 6 months. warranty "I don't know why they give warranty" even still we need pay. I buy this phone at amazon.com. new phone itself cost 20000k only.

So I've been my OPO for a year now and it's running on kitkat 4.4.4 cyanogen 11.0-XNPH05Q...I upgraded it to lollipop and immediately regretted it as the battery life went way to low and the interface kinda sucked (at least to me) but that was way back in July...So my question is the performance of the latest lollipop version that I'm gonna get...and what are the pros and cons of the latest lollipop version.
Thanks.

Anonymous_42, 23 Nov 2015How is the BATTERY LIFE.....Please do tell??I can't say -- I charge the battery every day. In order to preserve the life of the battery, I don't let the charge drop below 30 or 40 per cent (this is good practice for ALL smartphones). In my experience, however, a full charge will last a whole day of normal usage. You can drain the battery pretty quickly if you have the screen on all the time, e.g., watching movies, playing video games, etc.
